Evaluation of breathing dynamics using the correlation of acoustic and ECG signals

摘要: This research was aimed at finding a correlation between acoustic signals and heart activity parameters representing sleep disorders. The measurement of breathing through simultaneously acquired ECG is used to quantify the respiratory obstruction during sleep. It believed that dynamic characteristics this noninvasive technique allows for an inexpensive accurate analysis these events. recordings from number subjects were collect electrocardiogram-derived (EDR) rate variability (HRV) information. signal calculated using two methods: EDR. Comparison results indicates both methods are equivalent in assessment information collected by simultaneous effects partially overlapping, giving opportunity improve accuracy complementing, allowing extension aspect. Proposed data collection scheme more convenient can be performed ambulatory conditions.
